Someone knows how to find expiration date on Lancome make up?

I would call 1-800-LANCOME and ask them. Each product has a different shelf life.Someone knows how to find expiration date on Lancome make up?
make up doesnt expire because the ingrediants spoil, like food, it only expires because it has been opened and in use for two longer, and there are too many bacteria living in it. so make up that was made 20 years ago but has never been opened it more hygenic than make up youve had open for a week. on the back, it will have a graphic of an opened pot and either 3m, 6m, 12m, 18m, 24m, or 36m, to indicate how many months after you opened it it is safe to use. if you care loads (like me, i'm obsessed with stuff like that, i'm such a hygene dork lol) you can put a sticker on. if i opened a nu mascara 2day, i would put a litl sticker on it saying 'oct' to indicate i should through it away at the begining of october


(in about 6 months), because i no i wont rememba wen i bort it in a fu months time lol.
